Organisms with the Largest 'population' on Earth

This updated overview organizes the essential information about Organisms with the Largest 'population' on Earth, including practical uses, key features, setup considerations, and common questions.

1. Ants

Ants are one of the largest animals on Earth today. According to estimates by a team of experts led by biologist Mark Wong, there are about 10 trillion ants in the world. Their total biomass is up to 12 million tons, accounting for 20% of human biomass. Ants play an important role in the ecosystem, moving soil, distributing seeds and recycling organic matter.

2. Birds

According to research by the University of New South Wales, on Earth there are about 50 billion individual birds divided into 9,700 species. Among these, there are 4 bird species with more than 1 billion individuals.

3. Reptiles

Modern reptiles include lizards, snakes, turtles, and crocodiles, and are estimated to number about 10 quadrillion individuals.

4. Mosquitoes

Mosquitoes, belonging to the class of insects, grow mainly in stagnant and tropical waters. There are an estimated 1 quadrillion individuals globally.

5. Mollusks

The Molluscan phylum includes clams, oysters, snails, mussels, clams, squid, and octopus. This is the largest group of marine animals, with about 500 trillion individuals.

6. Fish

Fish live in most large bodies of water, at depths ranging from saltwater to freshwater. An estimated 3.5 trillion individual fish, divided into about 33,600 species, have been recorded.

7. Tree

The Earth currently has 3.04 trillion trees, a 46% decrease compared to the time humans appeared.

8. Chicken

With 24 billion individuals, chickens are the most numerous bird species. The chicken industry has grown dramatically since the 1940s, accounting for 23 billion of the 30 billion animals raised on farms.
